  • Pretreatment System for Forklift Truck Washing Operation

    Pretreatment System for Forklift Truck Washing Operation

    A major merchandiser maintained a large warehouse for distribution throughout the New England area. The facility washed electrically powered forklift trucks in a parking lot, allowing wastewater to flow into a wetland. Lead from battery acid caused the wetland to become contaminated, resulting in a violation order. A pretreatment system was needed for discharge to the municipal sewer. ERA conducted Continue Reading

  • Site Investigation & Remedial Design for Superfund Disposal Site

    Site Investigation & Remedial Design for Superfund Disposal Site

    ERA provided process evaluation, design and monitoring services for remedial actions to renovate contaminated groundwater beneath an uncontrolled, hazardous waste landfill. ERA conducted groundwater monitoring, and groundwater treatability studies to remove solvents, heavy metals and organic compounds. Bench and pilot scale tests were performed to evaluate state-of-the-art treatment technologies. Subsequently, ERA designed a mobile trailer-mounted treatment plant for the withdrawal, Continue Reading

  • Design of Air Pollution Controls and Local Ventilation for Uranium Ore Processing Plant

    Design of Air Pollution Controls and Local Ventilation for Uranium Ore

    ERA completed a design of air pollution control devices for a large grass-roots uranium ore processing facility to be located in southwestern United States. The facility will receive the uranium ore from nearby mines and process the ore to produce yellow cake. Operations at the facility are to include uranium ore stockpiling and transportation, conveying, SAG milling, screening, chemical leaching, Continue Reading

  • Vapor Intrusion through Concrete Floor

    Vapor Intrusion through Concrete Floor

    A manufacturing building situated on a thick industrial concrete floor overlaid groundwater that was contaminated with chlorinated¬†solvents. ERA retrieved and analyzed sub-slab soil gas samples from beneath the concrete floor in strategic locations to assess the likelihood of vapors migrating from groundwater into the workplace air. The soil gas results were high, indicating a potential risk to workers. This prompted Continue Reading
